My barn’s interior was sheathed with rough sawn pine 1×8’s that were butted together side-by- side and nailed. After some time the 1×8’s dried more completely and shrinkage gaps between each board began to emerge. is there any type of chinking product that could be used to effectively seal off these gaps?

thanks,

George in the North Georgia mountains
